* Apical meristem: Located at the tip of the stem, responsible for primary growth (increasing length of the stem).
* Vascular cambium: Located between the xylem and phloem, responsible for secondary growth (increasing girth of the stem by producing new vascular tissues).
* Cork cambium: Located in the outer layer of the stem, responsible for producing cork cells (protective outer layer of the stem) during secondary growth.
While these are the primary meristematic tissues in a dicot stem, it's worth noting that other meristematic regions might also be present, depending on the specific plant and its developmental stage. These include:
* Lateral meristems: Includes vascular cambium and cork cambium, as mentioned above.
* Intercalary meristems: Found at the base of leaves and internodes, responsible for extending the length of these structures.
The meristematic nature of these tissues means they have undifferentiated cells that can divide and differentiate into various specialized cells, contributing to the growth and development of the plant.
